Rotor-Bearing System Stability Performance Comparing Hybrid versus Conventional Bearings

Rotor-Bearing System Stability Performance Comparing Hybrid versus Conventional Bearings

New closed-form expressions for calculating the linear stability thresholds for rigid and flexible Jeffcott systems and the imbalance response for a rotor supported on a hybrid bearing are presented. For typical bearings characteristics, expressions yield stability thresholds practically equal to th...
